Question

Maya is camping at the top of Mount Armstrong at an elevation of 7832 meters. Juan is scuba diving 160 meters below sea level. The two decide to meet at the midpoint. At what elevation will Maya & Juan meet?

Answer 1

The midpoint elevation will be 3,836 meters.

Explanation:

Maya's elevation of 7832 can be represented by the positive integer +7832 since she is above sea level. Sea level would represent 0 on our number line. However, Juan is below sea level, so we can represent his distance at -160. When we add these two integers together +7832 + (-160) = 7672 meters above sea level. Since Maya and Juan are going to meet at the midpoint, we would divide our overall distance (7672) by two to get 3836 meters.

Answer 2

They will meet at 3836 meters

Explanation:

Maya is at 7832 meters

Juan is at -160 meters ( below sea level)

If they are meeting at the midpoint, we add them together and divide by 2

Midpoint = (7832 + -160)/2

= (7672)/2

=3836 m
